To all whom it may concern.'

Bef it known that I. Fonns'r FINLAY, a subjectof the King of (lrreat.Britain, residing at No. -10a Cannon street, Petershaln, near Sydney, inthe State of' New South llf'ales and Commonwealth of Australia,-mechanical engineerhave invented new and useful Improvements inRoller-Skates, of which the following is a specification.

This invention relates principally to extensible roller skates in whichthe frame is constructed with a fore or toe frame and an aft or heelframe each adapted to slide in or upon the other and he clamped inposition for the .purpose of adjusting the `length of the skate tovarying lengths of boots andshoes, etc.. Worn by,the users though partsare applicable to inextensible skates.

According to this 'invention the present improvements consist first inconstruct-ing the overlapping extensions or shanks of the fore orsolepiece and of the aft or heel piece of channel section s0 that amaximum 25 of rigidity is attained and expeditious and leasyadjustmentas to length or size of the skate sole is possible secondly informing the outer. of the brackets of the front and rear axle bearingsupports of a plece cut from `the sole of the Yskate and bent down-ywardly and outwardly thirdly in strengt-hening the toe of the sole andthe forward bracket of the front bearing support and atthe same timeproviding a bearing for the adjusting screw of tlie toe clips" b v a'rib or fin fourthly in strengthening the rear or( outer bracket of theback bearing support by a rib or finand fifthly in formingthe innerstayor brackets of lthe axle bearing supports with flanges or lips toengage the sides of, said bearing supports and so firmly hold same.

In order that a practical application of the present improvements may bereadily understood the same will be described with .reference to thedrawings accompanying and :forming part of this cation in which- Y*Figure 1 is a perspective view of a skate constructed with the presentimprovements incorporated. Fig. 2 is a sectional elevation completespecifionV the plane 2- 2 Fig. 1 looking rear# wardly. Fig. 3 a similarview on 4the -plane 3-3 Fig. 1 looking forwardly. -Fig.

4 is a longitudinal central sectional elevafrom the angle of line 8-8Fig. 4.

The sole piece 9 has its overlapping part or shank 10 of channel sectionpreferably of arched shape with slot. 11 and orifice 12 and the heelpiece 13 has-asimilar corresponding shank 14 and this has flanges 16slot 17 and orifice 18. The stem shank 10 and the shank 14 under oroverlap the siot 17 in the latter being positioned .above the orifice 12in the former and a clamping bolt 19 preferably with its head uppermostpasses through both and through orifice 20 in the stay' bracket 21 whichis attached to the front axle bearing supports of known construction andhas' flanges er lips 22 to y engage the sides of said bearing sup rts.

The slot 11 of the toe piece 9 trave s beneath the orifice 18 of theheel piece 13 and a clamping bolt 23 preferably with its head uppermostpasses through both and through orifice 24 in the stay bracket 25 whichis attached to the back axle bearing supports of known construction andhas flanges or lips 26 to engage the sides of' said bearing, supports. c

The front or outer bracket 27 of the front bearing supports is formedof' a -piece cut and pressed from the sole plate `28 and the toe of saidsole plate is supported and strengthened by a. rib or fin 29 riveted toor formed Ion the under side of the sole plate 28 with its rear end 30abutting and staying said bracket 27 and having a slot 31 forming abearing for the adjusting screw 32 of the toe clips 33. The rear orouter bracket 34 of the back bearing support is formed of a piece cutand pressed from the heel plate 13 and said bracket is stayed by a ribor fin 35 riveted to or formed on the under side of the said heel plate13.`

In use the skates may be extended and closed by loosening the bolts 19and 23 drawing the toe and heel pieces apart or pushing them togetherand are locked at the desired length by tightening said bolts.

The special construction of the overlapping extensions or Shanks of thetoe and heel pieces though preferred ofthe arched channel shape as shownmay be of any shape such formation of bracket for the axle bearingmanufacture of the skates the ribI orin shank portioii,'said shankportion being proy bracket of the back bearing supports.

as V channel soiuare channel or tapered fiat channel shape in section inwhich the clamping bolts may pass through both shanks and slide inandupon them sot-hat a maximum rigidity is attained while facilitating andexpediting adjustment of the length of skate without removing theclamping bolts the supports of a piece of the sole'plate or heel platesimplifies cheapens and improves the under the toe of the sole platestrengthens same and prevents it being bent and cracked and stays thefront bracket of the. front axle bearing supports and the rib or plateunder the heel of the sole stays the rear axle What I claim, and desireto secure by Let-- ters Patent ,of the United States, is 1. Inextensible roller skates, in combination, a sole plate provided With achanneled vided with a slot and an orifice and a heel j plateprovidedwith a channeled shank portion., said shank portion being provided withA an orifice and a slot, said channeled shank portions overlapping oneanother, one of? said channeled portions being slidingly positioned`within the other and the orifice in each shank portion registering withthe'slot f in the other shank portion. e f

2. lin roller skates, a foot supportingplate, outer and innerbracketsforming'an axle,I

bearing support, said outer bracket being formed out of the material ofthe plate and bent downward and outward and a down.-

wai-diy extending rib extending longitudinally with respect to saidplate and abutting the bend in said outer bracket- 3. ln roller skates,a foot supporting plat-e and downwardly extending, oppositely disposedouter and inner brackets, an axle bearing support positioned betweensaid brackets, said inner bracket being provided with inwardly extendingflanges adapted to engage the sides of said support and hold it againstlateral movement. i l

4. In extensible roller skates, in combination, a sole plate providedwith a channeled shank portion, said shank portion being provided with aslot and an orifice, and a heel i plate provided with a channeled shankportion, said shank portion being provided with l an orifice and a.slot, said shank `portions overlapping one another, clamping boltspassing through said orifices and slots to E hold the platesv inadjusted position, and laxle iii,
